Protecting

More than two decades ago, implementation of the Central Valley Project Improvement Act (CVPIA) began, bringing about a new era of fish passage improvement. Under the CVPIA, the Anadromous Fish Screen Program (AFSP) was created, which authorized federal funding for fish passage and fish screen projects. These contributions to the fish screen projects were matched with local and state funding.

Fish protected through this program include:

A fish screen creates a barrier The LARGER the pumps, the between the fish in the and the LARGER the fish screen. pumps used to divert water. water pumps This ensures that water moving through a screen does so no faster than one foot every intake three seconds, thereby creating no chance that even the smallest juvenile salmon would be impinged on a screen or even have its equilibrium disturbed if it is swimming by a diversion that is pumping at maximum capacity.

Birds Benefit, Too. Screens are constructed with gaps small enough Fish screens also allow water (not much larger than the thickness of a penny) management entities to divert water that not even the egg of an endangered or year-round, allowing diversions in the threatened species of fish could make it through. fall and winter months to provide habitat for the waterfowl, shorebirds, raptors and other species that utilize the Pacific Flyway. In addition to fish screens, other projects have been constructed in the Sacramento Valley to improve safe fish migration. This includes siphons to convey water and sophisticated barriers (such as the Knights Landing Outfall Gates and Wallace Weir projects) to keep adult salmon in the river as they migrate upstream.
